TRAIN-PIPE COCK AND OPERATING MECHANISM THEREFOR,

Specification of Letters Patent.

Patented N (W. 25, 1913.

Application filed October 28, 1811. Serial 1i 0. 657,253.

To all whom it may concern:

Be it known that we, EMORY B. DUNKEL and FRANK S. BOWMAN, citizens ofthe United States, residing at Lucknow and Harrisburg, respectively, inthe county of Dauphin and State of Pennsylvania, have invented new anduseful Improvements in- Train-Pipe Cocks-and Operating Mechanism FTherefor, of which the 'following'is a specification.

The invention relatesto a train pi cock used now as angle cocks forairbra e systems, .and more particularly to the class of angle cocks, andoperating mechanism there- I for.

The -primary object ofthe. invention is the .provislonof a cock of thischaracter in which the handle thereof is disposed beneath the same andmay be readily and quickly operated for the opening or closing-of thecock, without ,requiring an operatorgoing between the cars for thisur'pose, thereby avoiding the possibility of injury or the loss of life,resultant therefrom.

Another object of the invention is the provision of a train pipe cock inwhich the handlelthereof will be sustained or locked in its open orclosed position, so as to revent ting of the handle by reason of shocksand jars incident to the travel of a train, the cock beeither opened inreadily and easily-set in g sides of, the

or closed position from both car, thereby operator going between thecars when manipulating the cock. I

' A further object of the invention is the provision of a device of thischaracter which is simple in construction, thoroughly reliable andeflicient in o eration, and inexpensive in manufacture and installation.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts, as will behereinafter more fully described, illustrated in the accompanyingdrawings, and pointed out in the claim hereunto appended.

In the drawings :-Figure 1! is a fragmentary end elevation of a cap,showing the train pipe cock mounted fliercon and the opcratin mechanismtherefor constructed in accor ance with the invention. Fig. 2 is afragmentary bottom plan view of a car body, showing the train pipe cockand operating mechanism in position thereon. Fig. 3 is a avoiding thenecessity of the diametrically opposite points,

fragmentary side elevation. Fig. 4 is an enlarged side elevation of thetrain pipe cock. Fig. 5 is a bottom plan view thereof,

showing the handle inshifted position by dottedlines. Fig. 6 is adetailvertical longitudinal sectional view through the handle, showingthe locking pin in side elevation. ig. 7 is a verticaltransversesectional view through a portion of the body of the cock andthe handle.Fig. 8 is a perspective view of one of the hangers for the operatingmechanism. Fig. 9 1s a-perspective view of one; of the levers-of theoperatin mechanism. 'Fig.- 10 is a side elevation o a sli htmodification of av mechanism.

Similar reference characters indicate correspondin parts throughout theseveral views of t e.drawings.'

Referring to the drawings by numerals, 5 designates generally a portionof the body of a freight car, having mounted on its end sill 6 a couplerhead 7, and a bracket 8 for the brake rod 9, as. usual. Also suitablymounted beneath'the sills of the car,-in suitable brackets, is the trainpipe 10 provided at each end with a cock, presently described.

The train pipe cock comprises-a straight body 11 having rotatably fittedtherein the valve, with stem 12, the same being held againstdisplacement therein by means of a cap 13, and connected to this valvestem :is' the handle 14, the same being formed with a vertical socket 15in its thickened portion 16, the socket 15 being closed at its open endby meansof a removable screw plu 17 and working within the socket is a100 ing in 18, the same also working through a suita 1e guide opening 19opening through the inner face of the handle and communlcating with thesaid socket 15, the pin being designed to engage in beveled indentationsor notches 20 formed in the flattened face 21 of the body, so that thehandle 14 thrown position for either opening or closing the train pipecock.

Formed on and projecting outwardly from the flattened face of the body11, at are stop difgs 22, against which is adapted to contact the handle14, when being thrown to either open or closed position. 1

Suitably fastened to the end'sill 6 of the body 5, on opposite sides ofthe point of disposition of the angle cock, are hangers,

hanger for the operatmgwill be locked in its each comprising a rod "23,the same being bent at one end to form reversely disposed open loops 24,with which are engaged the vent swaying of'the hanger while the opposite end of the rod is formed with a guide eye 25, and through theseeyes of the said hangers are passed rods 26,.thcinner ends of whichare'su tahly connected to the free end of the handle i l, while theirouter ends proyect a convenient distance spaced from thepla'mes' of thesides of the car, and terminate 1n handles 27 to be grasped by anoperator,: so thatj uponpulling or pushing ,upon one of the rods'26 thehandle 1 of the angle cock-may be shifted for the operating of thetrainpipe cook; The push rod 26 is to bepushed or pulleduntil the handle 14comes in contact with the stop lug 22, thus when the handle 1i is pushedor-pulled to meet the inside lu 22,. the valve is opened andwhen thehandle 14 is pushed or pulled to meet the lug 22 on the outside of thebody of the cock, the valve'is closed.

By reason of the fact that the handle of the train pipe cock is operatedbeneath the train,- numer'ous accidents and troubles which arise fromprotruding bolts coming-in contact with the handle and closing the same,thus shut-ting off air in the remainder of the train, will be avoided,the handle being entirely out-of danger v I IngFig'. 10, there is shownaslight ,modification of hanger for supporting the rods 26,wherein'there is shown a rod 28 having a threaded end 29 provided withjam nuts 30 which permit the mounting of the saidrod 28 upon the sill ofa steel freight car,

the opposite end of the rod-being formed with a guide eye 31, throughwhich is passed the rods 26.

From the foregoing, taken in connection with the accompanying drawings,it is thought that the construction and operation of the invention willbe readily understood, without requiring a more extended explanation.

What is claimed is: I

A train pipe cock including a body and a turning plug mounted therein,said turning plug having a stem at its lower end extending below theunder side of the body and a handle attached to said stem, said bodyhaving stop lugs, on its lower side, on opposite sides ofthe stem and inthe'path of-the handle and also having spaced beveled notches in itslower surface, between said stop lugs,

the bevels of said notches extending in opposite directions and saidnotches being deepened at their outer sides, and a spring pressed pinmounted-in the handle and having a terminal rounded end to cooperatewith saidnotches and lock the handle in engagement :with the stop lugand permit movement of the handle in the opposite directionsundersuflicient pull in combination with means connected toth handle andprojecting in both directions and beyond, f I

to permit operation of-the handle from opposite points relatively remotetherefrom.
